  • Influence of PICC Ultrasound Guidance on Elbow Puncture and Catheterization and Its Complications: A Systematic Review

    Objective To systematically evaluate the influence of PICC (peripherally inserted central catheter) ultrasound guidance on success rates and incidences of complications of elbow catheterization. Methods The Cochrane Library (Issue 3, 2012), Library of JBI evidence-based nursing center, MEDLINE, EMbase, CBM, VIP, CNKI and WanFang Data were searched for relevant studies to influence on success rates of puncture and catheterization and complications from upper arm placement of PICC ultrasound guidance as well as conventional PICC placement from inception to March, 2012. The data were extracted according to the inclusion and exclusion criteria by two reviewers, the quality of included studies was also evaluated. Meta-analysis was conducted using RevMan 5.1, or only descriptive analysis was conducted instead. Results Eleven randomized controlled trials, five clinical controlled trials and four cohort studies were included, involving 4 052 patients. The results of meta-analysis showed that, upper arm placement of PICC ultrasound guidance combined with modified Seldinger technique was associated with significantly higher one-time success rates of puncture and catheterization than conventional PICC placement below the elbow, with significant differences (OR=4.71, 95%CI 1.97 to 11.28, P=0.000 5; OR=8.63, 95%CI 1.92 to 38.82, P=0.005). Conventional elbow catheterization had a significantly higher incidence of phlebitis than catheterization on the elbow that under the guidance of PICC ultrasound and modified Seldinger technique (OR=0.13, 95%CI 0.08 to 0.21, Plt;0.000 01). Conclusion Elbow catheterization under the guidance of PICC ultrasound combined with modified Seldinger technique has an obvious advantage in improving the success rates of puncture and catheterization and reducing the incidence of complications, compared with conventional elbow catheterization.

  • Discussion on Application Value of Hysteroscopy in Infertility

    Objective To investigate the application of hysteroscopy in pathological changes of infertility uterus. Methods The clinical data of 226 cases of infertility females receiving hysteroscopy from January 2007 to June 2009 in Sichuan Provincial Hospital for Women and Children were retrospectively analyzed. Results In 226 cases, hysteroscopic examination identified 147 cases of intrauterine diseases (65.04%), including 56 cases of intrauterine adhesion (24.78%), 32 cases of endometritis (14.16%), 27 cases of endometrial polyps (11.94%), 15 cases of uterine malformation (6.64%), 9 cases of submucous myoma (3.98%), 3 cases of endometrial tuberculosis (1.33%), 3 cases of uterus cavity narrow (1.33%), 2 cases of cervical internal relaxation (0.88%). No postoperative complications occurred, except for a small amount of vaginal bleeding.

  • Evidence of Ultrasound Screening to Pregnant Women on Fetus of Fetal Genital System Malformations

    Objective To define an evidence-based conclusion concerning ultrasound screening for fetal genital system malformations during pregnancy. Methods In order to assess whether or not ultrasound screening for fetal genital system malformations is effective and feasible, we searched The Cochrane Library (Issue 3, 2009), MEDLINE (1981 to 2009), ACP Journal Club (1991 to 2008), and BMJ Clinical Evidence (1999 to 2008) for systematic reviews, randomized controlled trials (RCTs), cohort studies, and controlled clinical trials. Results Five cohort studies and three crosssectional studies were retrieved. The results showed ultrasound screening detected fetal sex determination by the contour of the rump and the angle of the genital tubercle to a horizontal line through the lumbosacral skin surface in the first trimester. Scrotal size and penile length increases with gestational age for male fetuses, and by 32 weeks, bilateral testicular descent was observed in most cases. Ultrasonographic scans, fetal genetic studies, and hormonal assays of amniotic fluid can diagnosis certain diseases, fetal sex differentiation disorders, fetal endocrinal disorders, and chromosome abnormality. Conclusion The findings of this study should reassure physicians and parents alike that ultrasound screening is an reliable option for the prenatal diagnosis of fetal genital system malformations, but more randomized controlled trials are needed to further supply relevant evidence.

  • Analysis of Transvaginal Ultrasound Results of 1872 Healthy Women’s Endometrium in Yongchuan District

    Objective To investigate the endometrial thickness and echo patterns of healthy women, so as to provide a basis for the formulation of a standard to define normal endometrium in Chinese women. Method A total of 1872 married healthy women in Yongchuan District received transvaginal ultrasound examination. The endometrial sonograph was observed and endometrial thickness was measured for statistical analyses. Results In pre-menopausal women of different age groups, the endometrial thickness was increased and the endometrial echo was enhanced from the proliferative phase, ovulatory phase and secretory phase. The endometrial thickness varied significantly among different menstrual cycles, while no significant difference was observed in the endometrial thickness of a same menstrual cycle among women of different age groups. Pre-menopausal women had significantly different endometrial thickness when compared with post-menopausal women. Conclusion Through a general survey of women by transvaginal ultrasound, a large sample database can be established, which may contribute to the formulation of a standard to define normal endometrium in Chinese women and to help identify abnormal endometrium.
